将多个相同的名称转换为一个名称，并在laravel中将值求和

$items = [
    ['name' => 'A', 'value' => 1],
    ['name' => 'B', 'value' => 2],
    ['name' => 'A', 'value' => 3],
    ['name' => 'C', 'value' => 4],
    ['name' => 'B', 'value' => 5],
];

$grouped = collect($items)->groupBy('name')->map(function ($group) {
    return [
        'name' => $group->first()['name'],
        'value' => $group->sum('value'),
    ];
})->values();

// 输出结果
/*
[
    ['name' => 'A', 'value' => 4],
    ['name' => 'B', 'value' => 7],
    ['name' => 'C', 'value' => 4],
]
